Description

  The present invention relates to a method for knitting a warp knitted fabric, and more particularly to a method for knitting a warp knitted fabric whose dimensions change in the width direction.

  As a knitting method of a warp knitted fabric whose dimensions change in the width direction, for example, a method described in Patent Document 1 by the applicant of the present application is known. In the invention described in this document, an object of the present invention is to provide a warp knitted fabric manufacturing method and a warp knitted fabric capable of forming a warp knitted fabric having a scarahem at an edge easily and in good shape by knitting. As a means for that, the loop yarn and / or the insertion thread runner length is reduced from the reference, and the knitting between the wales of the thrown-off width portion is knitted narrower than the reference. By supplying the loop thread and / or insertion thread with a runner length increased from the reference, the width between the wales of the discarded width part is knitted wider than the reference, so that the narrow part and the wide part of the discarded width part are warped in the longitudinal direction. Are organized so that they appear alternately.

  In the above method, for example, the dimension in the width direction is changed by increasing or decreasing the runner length of the loop yarn by a predetermined amount with respect to the reference length, but the runner length is increased beyond a certain ratio with respect to the reference length. If this occurs, loosening or the like occurs, and if the runner length is decreased beyond a certain ratio, there is a problem that it becomes a tensioned state and it becomes impossible to obtain a preferable width increase / decrease state. Therefore, it is suitable for forming a relatively small dimension change part such as a scarahem, but it is difficult to form a dimension change part exceeding this.

JP 2004-339619 A (see paragraphs 0017 and 0018)

  The present invention has been made in view of the above problems, and provides a knitting method of a warp knitted fabric that can form not only a scalar hem but also a large dimensional change portion in the width direction.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a method of knitting a warp knitted fabric whose dimensions change in the width direction, and in each of a plurality of body fabrics connected via a discarded width portion, When the feed amount is supplied in a stepwise change with respect to a reference amount, the feed amount is reduced in a stepwise manner in the feed amount of the warp in one of the adjacent body cloth and the discarded width portion. On the other hand, when the feed amount is increased stepwise and the feed amount is increased stepwise on the one side, the feed amount is decreased stepwise on the other side.

In this case, as described in claim 2, the knitting structure may be changed by inserting the insertion yarn into at least the discarded width portion and changing the swing width of the insertion yarn. When the knitting structure decreases the warp feed amount in a stepwise manner, the knitting structure increases the swing width of the insertion yarn stepwise and increases the warp feed amount stepwise. For this, the swing width of the insertion thread is gradually reduced.
Of course, the insertion yarn may be inserted not only in the discarded width portion but also in the body cloth portion so as to change the structure.
By doing in this way, it is knitted so that the width dimension of one body cloth out of the discarded width part and the body cloth increases stepwise, and the width dimension of the other discarded width part decreases stepwise. Is organized as follows.

  Further, in the present invention, there is no need to have a throwing width portion between the body cloths. In this case, the warp knitting method is a knitting method of a warp knitted fabric whose dimensions change in the width direction, as described in claim 3, and a warp feed amount in each of the plurality of body fabrics connected via the discarded width portion Is supplied in a stepwise manner with respect to a reference amount, and when the feed amount is to be reduced stepwise in one of the adjacent body cloth and the discarded width portion, When the feed amount is increased stepwise and the feed amount is increased stepwise on the one side, the feed amount is decreased stepwise on the other side.

Also in this case, as described in claim 4, in each of the body fabrics, the knitting structure is changed by changing the swing width of the insertion yarn, and the knitting structure reduces the feed amount of the warp in a stepwise manner. In this case, the swing width of the insertion yarn is increased stepwise, and when the feed amount of the warp yarn is increased stepwise, the swing width of the insertion yarn is decreased stepwise.
By doing so, one of the adjacent body cloths is knitted so that the width dimension is gradually increased, and the other body cloth is knitted so that the width dimension is gradually decreased. Is done.

  When inserting the insertion yarn as described in claim 5, the insertion yarn may be an elastic yarn, and as described in claim 6, the change in the feed amount of the warp yarn and the knitting Organizational changes may be repeated between predetermined courses.

  In the present invention, the size in the width direction can be greatly changed by changing the feed amount in each of the body cloths or in both the body cloth and the discarded width part. In addition, it is possible to further increase the dimensional change in the width direction by inserting the insertion yarn and combining the change in tension due to the change in the knitting structure.

Hereinafter, preferred embodiments of the knitting method of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a structure diagram of a warp knitted fabric according to the first embodiment of the knitting method of the present invention, and FIG. 2 is a schematic plan view of the warp knitted fabric of FIG.
The structure of the warp knitted fabric of this embodiment is basically the same as the warp knitted fabric described in JP-A-2004-339616, and a plurality of body fabrics 10, 10,. It is integrally formed in a parallel state (in the wale direction). And between these body fabrics 10, 10..., A throwing width portion 20 is provided via a connecting portion 30. The body cloth 10, 10,... And the discarding width portion 20 are knitted from the loop yarn L1 and the insertion yarn L2, and the edge yarn L3 is knitted at each edge portion. The body cloths 10, 10,... And the discarded width part 20 are connected by a cutting thread L3 ′, and the body cloths 10, 10,. .

In the warp knitted fabric of this embodiment, the runner length (feed amount) is increased or decreased with respect to the reference value for one or both of the loop yarn L1 and the insertion yarn L2 at least in the discard width portion 20. Of course, the runner length (feed amount) may be increased or decreased with respect to the reference value in both the discard width portion 20 and the body cloth portion 10. In this case, when the feed amount of the loop yarn L1 and / or the insertion yarn L2 is gradually reduced in one (for example, the discard width portion 20) of the adjacent discard width portion 20 and the body cloth portion 10, the other ( For example, in the body part 10), the feed amount is increased stepwise. When the feed amount is increased stepwise on the one side, the feed amount is decreased stepwise on the other side.
As an example of the degree of increase / decrease, for example, as described in JP-A No. 2004-339616, the runner length reference value is 1000 to 1200 mm, and the runner length is in the range of 400 mm to 1600 mm. .

In the present invention, in addition to the loop yarn L1 and the insertion yarn L2, the insertion yarn L4 may be further knitted, and the swing width of the insertion yarn L4 may be changed in size. The insertion yarn L4 may be knitted only in the discarded width portion 20, or may be knitted in both the discarded width portion 20 and the body fabrics 10, 10,.
The swinging width of the insertion thread L4 is large in the narrow portion h and small in the wide portion H. That is, for either one or both of the loop yarn L1 and the insertion yarn L2, the swing width of the insertion yarn L4 is decreased as the runner length is increased, and the swing width of the insertion yarn L4 is increased as the runner length is increased. .

By increasing the increase / decrease rate of the runner length of the loop yarn L1 and the insertion yarn L2 and increasing the change in the swing width of the insertion yarn L4, the change in the width of the wide portion H and the narrow portion h can be increased. .
The runner length of the insertion yarn L4 may be constant or may be changed. When changing the runner length, the runner length is reduced in the narrow portion h, and the runner length is increased in the wide portion H.
When forming the edge of the body fabric 10 in a corrugated shape, while changing the runner length of one or both of the loop yarn L1 and the insertion yarn L2 in the knitting direction, change the swing width of the insertion yarn L4. Repeatedly in the knitting direction, wide portions H and narrow portions h are alternately formed.

FIG. 3 is a schematic plan view of a warp knitted fabric according to the second embodiment of the knitting method of the present invention.
In the second embodiment, the discarded width portions are not knitted, and the adjacent body fabrics 10, 10. In this case, the runner length of either one or both of the loop yarn L1 and the insertion yarn L2 is increased / decreased in each of the body fabrics 10, 10. When the feeding amount of the loop yarn L1 and / or the insertion yarn L2 is decreased stepwise in the portion 10, the feeding amount is increased stepwise in the other body cloth portion 10. When the feed amount is increased stepwise on the one side, the feed amount is decreased stepwise on the other side.

Further, as the runner length of the loop yarn L1 and / or the insertion yarn L2 increases or decreases, the knitting width of the insertion yarn L4 may be knitted while changing in size.
When the runner length is increased or decreased and the swing width is changed, the wide portion H and the narrow portion h appear alternately in the adjacent body cloths 10, 10. That is, as shown in FIG. 3, in one body fabric 10, where the swing width of the insertion thread L <b> 4 is large, the swing width is decreased in the other body fabric 10, and the swing width of the insertion thread L <b> 4 is decreased in one body fabric 10. The smaller part increases the swing width in the other body cloth 10. By doing in this way, the narrow part h of one body cloth 10 and the wide part H of the other body cloth 10 are adjacent to each other with the thread L3 ′ interposed therebetween.

Although a preferred embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment.
For example, in the illustrated example, one insertion thread L4 is inserted into each body cloth 10, 10,... And / or the discard width portion 20, but a plurality of insertion threads 20 may be provided.
In the first embodiment, the insertion thread L4 is inserted into both the throwing width part 20 and the body cloth 10, but the insertion thread L4 may be inserted only into the throwing width part 20.

  The present invention is not limited to socks and stockings, and can be widely applied to knitting of other tubular knitted articles such as shirts and gloves.

It is an organization chart of the warp knitted fabric according to the first embodiment of the knitting method of the present invention. It is a schematic plan view of the warp knitted fabric of FIG. It is a schematic plan view of the warp knitted fabric concerning 2nd embodiment of the knitting method of this invention.
